man this 4160 budget economy OEM style Holley carburetor is killing me I just can't get it to idle at 14.x Air Fuel Ratio

I have now nearly bottomed out the fuel floats by going one whole turn clockwise from bottom of site hole

I even replaced the 65 main jets for the smallest ones in the Holley tuning carburetor kit which were 64s and still the best it does is idle at 13.x

I know what is in need of adjusting the idle air bleeds or the idle restrictors neither of which are tunable on this carb without drilling things, and I don't want to do that

so next month after pay day I am converting this thing to a 4150 carb, I may even get the center hung float bowls that have the sight glass in them because this pull the plug out and watch fuel drizzle out when you bump the truck with your hips may have been cool in 1969 but it aint no longer
